Immortality and Cultivation: This old man seeks enlightenment through mere survival.

In a certain period of ancient times.

The two great worlds, 【Mountain and Sea Realm】 and 【Demon Abyss】, have experienced a rare celestial convergence in their trajectories!

The barriers between the two worlds are squeezed and collided under the immense force...

Ultimately, in a very short time, at certain weak points, some temporary passages leading to each other's worlds were torn open!

One of these cracks happened to appear in the desolate marshland.

The Mist Demon King... or rather, his true form is a leader of the [Mist Demon] race.

The demon detachment it belonged to was one of the vanguards who seized this fleeting opportunity and brazenly invaded the Mountain and Sea Realm from the Demon Abyss through the crack!

It was only through the counterattack of the ancient human cultivators, a long and bloody battle, and at an unimaginable cost, that they were finally repelled and suppressed...

That temporary rift has long since been completely healed by the passage of time and the self-healing power of the world's laws.

The Mist Demon King, however, was permanently suppressed beneath the ruins of an ancient sect.

The tradition was interrupted due to the great war.

Later cultivators in the Northern Sky Domain knew very little about that turbulent yet bloody and dark history.

Therefore, they mistakenly believed that the Mist Demons, who had lost the nourishment of demonic energy over the long years, were unique monsters of the marshes—Mist Demons!

This is the true origin of the Water Mist Demon!

"It's truly astonishing; I never imagined the Mist Demon would have such a background..."

Lu Zaian was still processing the shocking news, his heart filled with turmoil.

No wonder—

Occasionally, relics are discovered in the marshes, sometimes even fragments of divine weapons or profound martial arts techniques...

In ancient times, the barren marshes were a haven for cultivating immortality, with sects of all sizes occupying different islands...

But the arrival of the Demon Abyss Rift destroyed everything.

In the aftermath of the great battle, all sorts of demons and monsters proliferated in the marshland, making it unsuitable for cultivators to reside there for long.

Instead, it became an adventure destination.

"So, there are still many ancient sect ruins within the swamp, after all, more than one demon team invaded back then..."

Lu Zaian's thoughts were racing when suddenly, he remembered something.

"By the way, the embryo of the Nine Netherworld Avatar was described vaguely at the auction, as if it were an object from outer space... Could it be..."

Lu Zaian hurriedly searched for the remaining fragments of the Mist Demon King's memory.

After a long search, filtering out a large amount of chaotic and useless noise, we finally found a sliver of useful information:

Nine Nether Blood Spirit Embryo—

The unique and wondrous gestation of the third level of the Demon Abyss!

It takes countless years to form after absorbing the essence of demonic blood from the most yin and filthy place!

For the vast majority of demons, it is a great tonic for tempering their demonic bodies and nourishing their flesh and blood, with effects comparable to top-tier elixirs in the eyes of human cultivators!

More importantly:

After refining the Nine Nether Blood Spirit Embryo, you can also obtain the unique [Abyss Demonic Rune]. Activated by the secret techniques of the Demon Clan, it can greatly enhance the combat power of the demonic body!

"This...this is...so the demonic markings on Jiuyou's body had a secret?! I never knew that!"

Lu Zaian was startled.

He had previously thought that the demonic runes were merely the physical characteristics of the Nine Nether Blood Spirit Embryo, without delving into their purpose.

Unexpectedly, there were also accompanying demonic secret techniques.

If it weren't for a fortuitous coincidence that he absorbed the Mist Demon King's memories, Lu Zaian probably would never have discovered it!

"Activating the Abyss Demonic Runes allows you to enter the [Demonic Descent] state."

Physical strength, speed, nerve reflexes, bone toughness... all physical attributes will be comprehensively multiplied in a very short time!

However, this method places a great burden on the physical body, and during the [Demon's Descent], the body is filled with surging demonic energy, making it very easy to attract attention... and one might even be hated by everyone.

It seems this can only be used as a last resort.

Lu Zaian plans to pass on the [Demon's Descent] secret technique to Jiuyou later. Every bit of strength that his clone gains will also increase his own strength!

Arrive here,

The fragments of the Mist Demon King's memories have been mostly unearthed, with only one piece remaining.

"Let me see what secrets this last piece of memory holds!"

Lu Zaian immersed his soul in it, slowly analyzing it.

a long time--

He opened his eyes again, his eyes still filled with disbelief and shock!

"...The 'Ghostly Netherworld Tribulation' technique does not belong to the human race's Daoist methods; its origin...actually, it also comes from the Demon Abyss Demon Race!!"

Lu Zaian was speechless for a moment.

Who knows?

As a dignified human cultivator, his strongest techniques, such as the Nine Netherworld Avatar and the "Netherworld Tribulation," actually originated from the Demon Abyss.

Memory display.

"The Ghostly Wheel of Calamity" originates from another extremely strange and unique race in the Demon Abyss—

【Ghost Demon】

Unlike other demon races, this race possesses a powerful physical body; instead, they are born with only a soul.

It takes on countless forms and is shrouded in mystery.

Therefore, the Ghost Demon race developed many secret techniques for refining soul power and improving their soul cultivation.

It can be described as unique.

The Ghostly Wheel of Calamity is one of the top techniques within their race.

They grow by devouring each other, like raising poisonous insects!

This is quite in line with the demon race's consistent style of survival of the fittest.

Unexpectedly, this demonic art also spread to the Mountain and Sea Realm along with the invasion of the Ghostly Demon.

And by a twist of fate, Lu Zaian obtained and cultivated it.

"...Wait, it seems that the Mist Demon King still has some fragmented images of the Ghost Demon Clan's invasion in his memory."

That place... seems to be some corner of a marshland?!

Lu Zaian focused intently on the past, his pupils dilating slightly.

My memory vaguely recalls that in a certain area near the Maple Domain in the watery region, there also seems to be the ruins of an ancient battlefield.

Its scale may not be as large as the Sword Tomb that suppressed the Fog Demon, but its level of danger is even greater.

Deep underground... there is a seal, or rather, a pile of remnants of the souls of countless ghostly demons!

Through countless years.

The intertwining of resentment and soul power has turned that place into a forbidden zone for spirits that no living person can approach!

For other cultivators, it was an extremely dangerous place; touching it meant certain death.

But for Lu Zaian, who has cultivated the "Ghostly Netherworld Tribulation," it may become a huge treasure trove of "resources."

That's enough to cause his spiritual power to surge!

"It seems that after I break through to the Core Formation stage, I will need to explore the ruins near Maple Birch Domain."

Lu Zaian memorized this message.

But now is not the time.

In my memory, that ruin was frequented by many remnants of third-tier ghost demons.

With his current cultivation level, he'd probably be going there not to devour resources, but to provide the opponent with "extra food"...

At this point, the memory has been fully digested.

All the secrets and the massive flow of information have finally been sorted out.

"call……"

Lu Zai'an let out a long sigh, feeling somewhat exhausted, but even more so, a great sense of fulfillment.

"Let's take it one step at a time. I'll start with the cultivation of the 'Azure Dew Extension Technique'... A third-tier wood-type cultivation technique, it might double my cultivation speed!"
